The MC is the main character of this story aside from Monika who as survived the same week repeating itself over and over again.

The description below describes how the MC USED to act towards the other members. In this iteration of the MC, he is desperately trying everything in his power to save everyone with a spefic interest in saving Sayori's life specifically. He blames himself for her suicide over and over and over again. In this story, he remembers everything happened, but the other members have no memory of the of the week of hell where they died again and again. He alone carries the burden of their suffering. He believes that only he can save them. However he is sorely mistaken in thinking he can break the cycle for good alone.

The protagonist was designed to function like a typical visual novel protagonist. He acts blunt and mean towards Sayori, his childhood friend; teases Natsuki, the tsundere; is warm to Yuri, the shy girl; and falters around Monika, the popular girl. According to Dan Salvato, he is deliberately given very little focus.[2]

More specifically, the protagonist is an underachiever, preferring to play video games and watch anime instead of applying himself and having friends. Despite this, when he does interact with others, he tries to be kind and thoughtful. He takes note of how people around him are acting and feeling, although more subtle things may go over his head. He is shown to be clever and observant in Act 1.

He tries his best to help even when he is out of his depth, as seen when he tries to ease Sayori's depression, despite not understanding it.

He shows a distaste towards those who are judgmental, shown by a scene in Natsuki's route, and in Yuri's route, he is accepting of Yuri's interest in knives, highlighting an open-minded personality.

The protagonist is true to his word and always attempts to keep his promises; he works harder if he knows people are counting on him.

Although the protagonist's primary interests are self-oriented, he does show a liking towards "cute girls", deciding to join the Literature Club on the basis of cute girls attending.
